New mount for Stanton Inside Drive

    I recently completed a new mount for my Stanton inside drive kit, and did away with almost all of the universal parts of the mounting kit. I wanted to get the engine as close to the seat and as low as possible.
    The main mount is made from a marine grade of plastic called StarBoard. Its a UV stable polypropolene. I machined in slots to match up to the frame perfectly so it could not twist or slide down. I also installed stainless steel Helicoil threaded inserts to improve thread strength. I have 175 miles on it since the make over completion without any problems. I think it came out looking pretty clean, let me know what you think.

    Looks like you did a right fine job with that. A good idea made better, perhaps.
    Let us know how the polymer holds up.

    "Let us know how the polymer holds up."

    Will do. I have 175 miles on it so far with no apparent issues. I was going to make it out of alluminum but I had the plastic on hand and thought what the heck I'll give it a shot.

    That Starboard is cool.. I used it on my boat, It's easy to work with you can drill, saw or route it.

    Looks like you skipped or eliminated the right side rear support. Any performance issues related to that?
    Also, I see a down pipe or something on the exhaust. What's that?

    The front mount is so solid that I didn't feel I needed to go through all the extra work to put the right rear strut on. There haven't been any issues without it.
    As far as the exhaust goes, I had some 1/2 inch thinwall tube laying around the shop that fit perfectly onto the R/S exhaust tip. I bent a 90 in a short length of it, and tacked it on with the TIG. Just by directing the exhaust downward reduces the volume a bit.

    Other than volume, did you notice a performance issue with that mod? Plus, minus?

    No, I have the exact same top speed, and haven't noticed any difference in low end performance.

    I'm also digging the front carrier. How'd you fab that? What's the platform made of.

    That is made of 1/2 inch OD thin wall steel tubing. I used a 1/2 inch hand tubing bender to form the 2 corners. I copied a rack I saw on this web site.

    Great work on the mount! Paint it to match your bike with red or black and it'll look good.

    I was curious why you decided not to just cut the Staton mounting bracket about 3 inches shorter and drill new holes for the support bolts. I'm preparing to mount an outside chain drive this weekend and that's my plan so far, but was wondering if there's any potential issues I may have overlooked.

    The Stanton mount will do the job just fine. I could have cut their mount and redrilled it. I just wanted to eliminate all wobling and sway. I was about to make it out of solid aluminum, but I had the plastic and it is great stuff to work with. As for painting it, StarBoard doesn't take paint very well, but I may try that Krylon paint thats made for plastic. The upside to leaving it as is, is that if it gets scratched its the same color all the way thru.
